To all whom it may concern 3 Be it known that I, HUoo R. 'WI'NTON, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Strainers and Fish Traps for Water Lines, of which the following is a specification. i This invention relates to strainers and fish traps for waterlines, and hasfor its principal object to permit them to be easily and quickly cleaned withoutputting the lines out of service and at the sametime preventing the lines from being. left unprotected.

A further object of the invention is to provide interlocking meansbetween a plu- A further object of the invention is to.

Fig. 3 is a longitudinal sectional view showing with solid lines the primary strainer in cleaning position and the secondary strainer in operating position, and with dotted lines the primary strainer in op erating position and the secondary strainer in cleaning position; and I F ig. 4. is a transverse sectional view on the line 4-4 of Fig. 1. 5

The invention is here embodied in a .con-

,n-ection for water linesandincludes a casing 10 having a chamber 11 therein, which with the inlet 12 and the outlet 13 forms the main passage of the line. A by-pass 14 leads off from the side of the chamber to a suitable valve or the like and is used for blowing out the trap to clean it and the strainer. A strainer 15 pivoted in the sides of the connection isadapted to swing across the main passage and lie against a ledge 16 to divide the chamber 11 into a primary trap and a secondary trap. The axis 17 of the strainer strainer 15.

15 preferably lies across the by-pass 14 and the strainer is equipped with. a valve 18 that normally lies across the by-pass at the edge of the primary trap.

The secondary trap is equipped with a strainer 19=pivoted at 20 and normally lying against a ledge 21. One side 22 of the casing. is preferably removably secured thereto as by bolts 23' and the strainers are preferablymounted in this side plate so astobe assembled and dismounted therewith. The shaftsof the; strainers areequipped, with. stuffing boxes-24 atth'e end. carriedby the. plate 22' and their opposite ends fit into suitable hearings in the fixed-side The ledges 16, and. 21 preferably extend across three sides of the casing'and afford. a fairly tight'joint with-the frames. ofthe strainer. 1S normallystop all foreign matter coming strainer-19 is chiefly of service when the strainer 15; is being The strainer 15 and the valve cleaned though it may also s'erveto strain out theqfiner particles that get by the Normally both strainers'hlie across the main passage.

In order t'dinsui nia one ofthe s will always lie across the main passage, prefer to interlock the strainers so that :iovement of one of them from its normal osition will lock the other in that position.

As illustrated in the drawing, the strainer 15 is equipped with a segment 27 having q, curved surface 28 lying on an arc whose center is in the axis 17. The segment is also provided with a curved groove or slot 29 lying on an arc whose center is in the 30 about which the strainer 19 swings. The strainer 19 is equipped with an arm 31 having short segment 32 which carries a lug adapted to move along the slot 29 :r to cooperate with the curved surface 28 s conditions may require. The segment 7 is equipped with an arm 34 having a iandle 35 by which the segment and the trainer 15 may be moved, from normal osition to cleaning position. The arm 31 has a similar handle 36 by which the screen 19 and the segment 32 may give similar movement. When the stuffing boxes 24 project laterally from the side 22 it will be convenient to provide this side with a curved flange 37 adapted to support the segment 27 and prevent it out of cooperating relation with the lock l Vhen it is desired to clean the trap, the handle 35 is grasped. and the strainer 15 swung to the solid line position in Figs. 2 and 3. This moves the segments 27 from the solid line position shown in. Fig. 1 to the solid line position shown in Fig. 2 in which the curved surface 28 lies in the path of the lug 33 and prevents the strainer 19 from leaving normal position.

After the strainer 15 and the primary trap have been cleaned, the parts are restored to the position shown in Fig. 1 and then the handle 36 is moved to swing the strainer 19 and the arm 31 from the position shown in solid lines to the position shown in dotted lines in Fig. 2. This movement places the lug 33 in the passage 29 and thereby locks the segment 27 and consequently the strainer 15 in normal position. By making the passage 29 substantially the same width as the lug 33 and locating the log 33 close'to the surface 28, a very slight movement of one of the strainers from normal position serves to lock the other strainer in that position until the first strainer is returned entirely to seated position against its ledge. This insures that one strainer will always be across the main passage and tight against its ledge so as to protect the line leading to the building.

The construction illustrated is simple and effective and it permit-s the casing, the frames and the strainers and the interlock ing elements to be cast in a form ready for use and limits the machine work to the stufiing boxes and the joint between the from being bent removable side and the remainder casing. This makes it possible to ufacture the device very cheaply.

I am aware that changes may be made in the form, construction and arrangement of the invention, as set forth in the selected. embodiment herein, without departing from the scope or sacrificing any of its material advantages, and I therefore reserve the right to make all such changes as fairly fall within the scope of the following claims.

I claim:

1. A water line connection having a main passage and a by-pass a plurality of strainers arranged across the main passage to strain the water passing therethrough and adapted to swing in position across the by-pass, and means to insure that one strainer will always be across the main passage.

2. A water line connect-ion having a main passage and a by-pass, a plurality of strainers normally lying across the main passage and mounted to swing across the by-pass, and interlocking means connected with the strainers to prevent all of them from being swung across the by-pass at one time.

3. In a water line, a connection having a main passage and a by-pass, a pair of strainers each pivoted to swing from a position across the main passage to a position across the by-pass and means operated by the swinging movement of one strainer to prevent swinging movement of the other strainer.

4. In a. water line, a connection having a main passage and a by-pass, a pair of strainers each mounted to swing from a normal position across the main passage to a cleaning position across the bypass, and interlocking means connected with the strainers permitting either to move freely when the other is in normal position and preventing either from moving when the other is in cleaning position.

5. In av water line, a connection having a main passage and a bypass, a pair of strainers normally arranged across the main passage and adapted to swing to a cleaning position across the by-pass, and cooperating means connected with the strainers adapted to lock either strainer in normal position when the other strainer is moved from normal position.

6. In a water line a connection having main passage and a by-pass, a pair of strainers mounted to swing from a normal position across the main passage to a cleaning position across the by-pass, a segment carried by one strainer, and means carried by the other strainer cooperating with said segment to maintain one of the strainers in normal position.

7. In a water line, a connection having a main passage and a by-pass, a pair of strainers mounted to swing from a normal position across the main passage to a cleaning position across the by-pass, a sector carried by one strainer and having two arcuate surfaces, and means carried by the other strainer cooperating with said surfaces to locli one strainer in normal position when the other is moved away from normal position.

8. In a water line, a connection having a main passage and a by-pass, a pair of strainers pivotally mounted in said connection to swing from a normal position across the main passage to a cleaning position across the by-pass. means carried by one of said strainers and having an arcuate surface disposed concentrically with respect to the axis of that strainer, and a second arcuate surface adapted to be arranged concentrically with the axis of the other strainer, and an arm carried by the other strainer having means cooperating with said surfaces to interlock said strainer.

9. In a water line, a connection having a main passage and a by-pass, a strainer adapted to swing from a normal position across the main passage to a cleaning position across the by-pass, a valve mounted to move simultaneously with the strainer from a position across the by-pass to a position along the by-pass, and a second strainer adapted to swing from a normal position across the main passage to a cleaning position across the bypass. v

10. In a water line, a connection having a main passage and a by-pass, a strainer adapted to swing across the main passage to a cleaning position across the bypass, a valve adapted to lie across the by-pass when the strainer is in normal position and to swing into the by-pass vwhen the strainer moves towards cleaning position, and a second strainer adapted to swing from a normal position across the main passage to a cleaning position across the by-pass.
